For example, the first holder 150 may move in a first direction (①), and the second holder 160 may move in a second direction (②). In the display 140, as the first holder 150 and the second holder 160 move in opposite directions, the first end 141 moves along with the first holder 150 in the first direction ①. And, the second end 142 can move along with the second holder 160 in the second direction (②). The second roller 130 may rotate clockwise based on the drawing. For example, the display 140 is formed by rotating a part (eg, the first part 144) of the rear surface (eg, the second surface 140b) and another part (eg, the first part 144) by the rotational operation of the second roller 130. The rear surface (eg, the second surface 140b) of the two parts 145 may move in opposite directions while sliding on each other.
